PREFACE

There is a worldwide revolution in small computer technology under

way and scientists are struggling to find ways to utilize this new

technology to help solve development problems in the Third World. We are

pleased to announce a number of papers on microcomputers in international

agriculture will be published in our International Development Papers

series. The aim of these papers is to provide timely information about the

rapidly changing state of the new micro-processing technology and its use

in research. The papers are also intended as guides to agr icultural and

social scientists on choosing, installing, and maintaining microcomputer

hardware and software systems in developing countries.

Some of the papers will also document field experiences of selected

established projects using new data processing hardware and software.

Other papers will concentrate on developing guidelines for establishing and

maintaining successful microcomputer and/or programmable calculator

installations for agricultural research in developing countries.

The present paper is the sixth of these new papers. It is based on

staff work by faculty members and graduate students of the Department of

Agricultural Economics, Michigan State University, on cost-effective data

collection, management, and analysis techniques for developing country

applications. This activity is carried out under the terms of reference of

Food Security in Africa Cooperative Agreement DAN-1l90-A-00-4092-00,

and previously under Alternative Rural Development Strategies

Cooperative Agreement DAN-1l90-A-00-2069-00, between the Bureau of

Science and Technology of the United States Agency for International

Development jand the Department of Agricultural Economics at Michigan

State University.

Readers are encouraged to submit comments about these new papers

on microcomputers and to inform us of their activities in this area. Write

A. INTRODUCTION

I. Background

The last three years have witnessed the advent of a large number of

increasingly powerful microcomputers and a proliferation of application

software for these machines. The wide range of statistical software

available makes the selection of appropriate, cost-effective packages

difficult, especially with time deadlines and high search costs. In light of

these problems, this report has two major objectives: (1) to provide detailed

information about comprehensive general statistical software which gener

ally have a price range from $100 to $1,000; and (2) to provide information

on other statistical and related software of special interest to those desiring

to use microcomputers to conduct socioeconomic data analysis.

For optimal choice of statistical software, information about the

following issues is usually necessary: (1) hardware and language require

ments; (2) cost; (3) ease of program use; (4) documentation adequacy and

ease of use; and (5) source. More technical questions include: (1) the

statistical routines included and statistics calculated; (2) data and calculat

ing capacities; (3) accuracy and speed of calculations; (4) flexibility and ease

of data management and file use--particularly with respect to ease of data

transfer between the statistical package and other programs; and (5) reli

ability of program operation and warnings about incorrect procedures. In all

statistical programs listed in this report, name, cost, source, language and

operating system, hardware requirements, and some descriptive information

about the programs have been listed. Intensive evaluation is currently

underway by MSU staff on six of the comprehensive statistical programs

(see footnote to the Index of the Comprehensive Programs). The results of

this evaluation will be published in a forthcoming MSU International

Development Working Paper.

Although we have attempted to provide a comprehensive picture of

software for the most popular microcomputers, new programs will continue

to appear. We believe this is a fairly complete report on current programs

which are easily obtainable. The information presented has been obtained

from promotional material, microcomputer journals, program manuals, re

views, and correspondence with producers and users, as well as from

personal experience with some programs.

Software development for microcomputers is proceeding very rapidly.

Microcomputer statistical software development in the near future will

probably: (I) assume the use of larger microcomputer memory (e.g.,

128K RAM) and (2) the integration of statistical with more comprehensive

data base management, word processing, and graphing routines.

2. Organization of the Report

This report is divided into two major sections. The first section

focuses on comprehensive statistical software, and the second on other more

specialized (and/or limited) statistical and related software for socioeco

nomic data analysis.

a. Comprehensive Statistical Software

In this section, we present information on 31 "comprehensive" pack

ages which are easily accessible. These are listed in Table I where price,

computer, and key analytical features are also identified for each package.

To be classified as "comprehensive," these programs generally have to

include descriptive statistics, cross-tabulations, correlation analysis, and

regression. They often also include analysis of variance, and some minimal

graphics. In this section, in addition to providing general information for all

packages, we have presented considerable technical information, especially

on: (I) the routines included; (2) capacities; (3) data interchange; and

(4) whether routines are menu-driven. In each review, we have also listed

some positive and negative comments based upon first-hand experience of

the authors and others in using the programs, and on references to published

reviews of the programs. Sources of information are indicated. Each

description in this section may include additional information about the

programs, such as sample printouts, graphics, a list of commands, and other

technical material.

b. Other Statistical and Related Softwarefor Socioeconomic Data Analysis

In conducting our review, a number of more specialized and/or limited

software programs were also identified which appeared likely to be of

interest to agricultural researchers and other analysts. This section

describes specialized software for: (I) statistical analysis; (2) trend analy

ses; (3) survey data processing; (4) graphics; and (5) linear programming.

These programs are listed in Table 2 along with price, computer, and key

analytical features of each package. The software descriptions (or

annotations) in this section are brief, compared to those in the "comprehen

sive" section. There are a large number of packages listed here, most of

which we have not examined in the same degree of detail as those in the

"comprehensive" section. As can be seen when reviewing Table 2, the

packages tend to be more specialized and contain fewer features than those

in the "comprehensive" section.

Although some "comprehensive" statistical software have trend (time

series) analysis routines, users needing high performance programs for time

series analysis may want to consider more specialized programs. The same

logic applies to specialized programs for processing survey data. In using

these, particular attention should be paid to the type of data files produced

to ensure compatibility with the desired statistical software (mainframe or

microcomputer). Note that, although many plotting or graphic programs are

available, the majority appear to have quite limited flexibility.

3. Comments on Analytical Features

An interesting characteristic of the statistical software identified in

the two sections is that the price often has little relation to the quality of a

package. There are some US $1000 packages which offer little more than

US $200 packages. There are also a few US $200 packages which offer little

more than programmable calculators. It is therefore important for potential

buyers to read software descriptions very carefully.

Advertising literature generally gives a few details about types of

analysis performed plus a few samples of the printout. Almost none give

details about data entry procedures, which absorb much user time. As

always, it is important for buyers to know as exactly as possible the types of

analyses they want to perform and then to look for packages that will carry

them out. If a software package is used only occasionally, then a menu

driven package may be adequate; but if it is used daily or weekly, then the

user may benefit from the flexibility of a command-driven package. If using

only one type of analysis such as regression, then a specialized package may

well serve better than a generalized one.

A number of highly specialized programs appear to have advantages

for users with a heavy load of statistical analysis. These include the

following software (also shown in Table 2): ANOVA II, LOLITA, Sample

Calc, STAT POWER, Statmanager, Stat Plus, Statistics (Keller Software),

and Stepwise Multiple Regression.

There is very little software available to assist experimental design or

for analysis of experimental data. Nearly all of the software is written for

analysis of social science data. Although there are several packages that

can accept and analyze experimental design data, they are relatively

complicated to use and do not employ vocabulary or formats familiar to

experimental design users. For this and other reasons, a group of agricultur

al scientists at The Agricultural University of Norway and at Michigan State

University have developed "MSTAT," which is comprehensive for experimen

tal design, data management, and statistical analysis. Preliminary versions

of the program are being tested in Michigan, Norway, and Peru. A brief

description of "MSTAT" is included in Annex 1 of this report. The expected

release date for the program is January 1984. It will be made available in

Third World Countries through USAID and other donor development projects.

a. Trend Analysis FWlctions

Software with trend analysis functions consist of packages expressly

written for analysis and/or forecasting of econometric time period data such

as prices or volume of product. A package has been noted as performing

trend analysis functions if the vendor's literature stated that the software is

intended for trend analysis use. In other cases, a trend analysis function is

noted if special features are included such as (I) Box-Jenkins analysis;

(2) extensive regression analyses; (3) extensive curve smoothing or transfor

mation abilities; and (4) other specialized functions such as seasonal adjust

ment or spectrum analysis. Stock market packages have not been included:

although technically these have trend analysis functions, they are not

relevant for most developing countries. Trend analysis packages of particu

lar interest include Micro TSP, Speed STAT-4, TWG/ARIMA, EAST/ARIMA,

and VISITREN/PLOT.

b. Survey Data Processing Ftnctions

Survey data processing features are found in comprehensive and/or

specialized statistical packages, and in stand alone packages that have the

capability to enter, check, easily edit, store, recall, and redefine survey

data. There is frequently little information available about the data entry

procedure. This is unfortunate since most of the time spent in survey data

processing is for data entry. There is likewise little information about data

cleanup facilities. Most of these software packages offer routines for data

12

entry, data cleanup, and limited summary functions such as cross-tabulation

or descriptive statistics. For many small surveys, this would be adequate.

For more complicated analysis, it is important that the package be able to

pass its data files on to another statistical analysis package.

Nearly all of these packages are limited in the number of question

naires or questions that can be processed. A few have the ability to process

large volumes of data but these tend to be more difficult to operate.

Programs noted of particular interest include ISIS (Interactive Statistical

Inquiry System), Microquest, Micro Survey, Personal Data Analysis, SNAP,

Survey Data Processing, and the Survey System.

c. Graphics Functions

Graphics functions include the ability to produce line charts, bar

charts, pie charts, or scatter plots. We have not reviewed programs to

produce slide show, animation, or lettering graphics. Many statistical

packages include bar chart or scatter plot output but frequently the quality

is minimal. Many graphics packages also include statistical features such as

linear regression and polynomial curve fitting. Some graphics packages are

general purpose and will produce a variety of charts with many fine

adjustments and text styles.

Certain key features should be kept in mind when looking for a

graphics package. The first is the ability to produce a chart on a wide

variety of dot matrix printers and pen plotters. If the user cannot get

replacement pens for a plotter, at least black and white charts can be

produced on a dot matrix printer. The second important feature is the

ability to add text in different fonts or styles of letters. Many times you

can design your own symbols or add non-English alphabets such as Arabic or

Devnagri. This feature greatly enhances the appearance of charts. Even

simple bar charts appear hand-drawn when fancy letters are used in the

title.

An important difference among graphics packages should be noted.

Most graphics software produces a paper copy using screen dump subrou

tines. The video screen image is reproduced on paper. Usually this results in

"blocky" circles or "stepped" curves and lines. The smoothness of the curves

depends entirely on the smoothness of the lines produced by the computer on

the monitor. No change of printers will improve the paper copy. The best

quality charts are produced by pen plotters. These do not reproduce the

13

screen image but actually draw the chart again using special subroutines

written for a specific plotter. Lines and circles appear to be smooth and

continuous. Different colors can be used simply by changing pens. If the

user needs charts similar to hand-drawn graphs, be sure to get a plotter

package that will interface with your plotter or vice-versa. Also, order lots

of plotter pens since they dry out fast in the dry season. If you do not need

high resolution charts, a dot matrix printer will do very well. There are

even color dot matrix printers on the market now.

d. Linear Programming Functions

The list of linear programming software is incomplete. It is likely that

a number of programs exist in colleges and universities just waiting for

someone to ask for a free copy. The programs included here are generalized

LP packages. Specialized LP packages for livestock rations, scheduling,

et cetera, have not been included.

The advertising literature for LP packages is remarkably free of

details about the software. In many cases, it was impossible to learn details

about a package (e.g., limits on numbers of variables or the types of results

produced). Fortunately, many LP packages are relatively inexpensive.

AIDA: Apple Interactive DataAnalysis

AIDA is a command~riented statistical analysis'package' for the Apple n. It provides the data manipulationand statistical conunands commonly needed in commercialor academic social science and marketing research. It is athome in other fields of research, as well - anyw-here theanalyst must deal with large quantities of infonnation.Time lag transformations and a powerful regression package make it useful in economics, too. Its statistics cover therange from descriptivf', thrnugh bivariate, 10 multivariatetechniques, with case weighting.

AID\. allows up to 11,CXX> data points in memory at once(e.g., SOOcases by 22 variables). with a maximum of over4,OCO cases, A 'virtual memory' system recalls variablesfrom separate binary disk fi1es as they are referenced duringanalysis; this pennits larger data files (up to 254 variables)than the computer can hold in memory. Program overlaylets AIDA run in under 8K.

•Apple II is a regist..red trademark 01 Apple Computer, Inc.

Analyses can be done on suh-sets of cases. selected eitherby case number or data values. Data may be transformedseveral ways, including any legal Applesoft statement.Data are entered either from the keyboard (with prompting), or from disk text files. Missing data. print to disk orprinter. and user-written routines are supported.

The price of the AI£lo\ program is $235.00, with a 20 percent student discount available, This includes the openCOS 3.3 program disk, one protected boot' disk, and over50 pages of documentation and sample output.

AIDA - Apple Interactive Data Analysis

The U.K. AIDA; one of two very different programswith the same name. Menu driven. Emphasis is on timeseries analysis but there is a facility to handlecross sectional data. Ordinary least squares, multiple regression, 2 stage L.S., auto-regressive estimation technique (Cochrane-Orcutt). Linear, log, andquadratio functions estimated by OLS and report writing. Comprehensive color graphing up to 4 series,data manipulations. Forecasting and Trend analysiswith 2 smoothing options. Exponential smoothing, moving average. Paper graphs are actual plots not screendumps.

Apple II with 64K and 2 disk drives, Apple lIewith an 80 column card. ITT 2020, 64K RAM,(USCD Pascal version 4, version for harddisk systems). Working on an IBM-PC version.

Are you asked to analyse or present data on your organisation's past or futureperformance. Do you want to explain the relationship between say, your sales andchanges in advertising or competitors' prices? Or perhaps you want to examinevariations in critical production figures. If you are interested in this type of workbut do not have the time or manpower to collect. store and analyse the numericaldata by hand, AIDA can help you,

Combined with an Apple II micro computer the AIDA program will allowthe user to subject any series of observations (for example, on prices, productionor sales data) to technical analysis and graphical display. New series can be produced from original data using simple arithmetic formulae or from combinationwith other series (to produce market share ratios, for example, or failure ratesl.You can chart this year's results against any other year or against as many as threeother series simultaneously. When linked to a plotter excellent copies of any graphor histogram you wish can be reproduced within seconds in full colour.

Statistical analysis may be carried out on data to help understand the behaviourof specific series (with the usual statistical tests). Alternatively, the forecastingoption allows you to approximate the underlying trend of a series and use it toforecast future values. The program also gives you the facility to make up tabulatedreports of the data used in any analysis.

AIDA stands for Apple Interactive Data Analysis

Here are more details of the various functions available in the program:

GRAPHICS. Up to four series can be simultaneously graphed on the screen. The user canproduce line charts, bar charts or a histogram from data on one series, and a scattergramof two series. Graphs of two or more series can be automatically scaled and, at all time:.;,it is possible to graph part or all of the data available. Transfer of any graph from the screento paper may be done using a Watanabe plotter (for full colour copies) or by means of anEpson or Anadex printer (black and white copies but not screen dumps).

STATISTICS. AIDA offers comprehensive, but easy to use, statistical options. Cross-sectional(survey) and time series data can be handled by the program. Regression procedures include;ordinary least squares, two·stage least squares, and an iterative autoregressive estimationmethod. The user may estimate models involving lags, different transformations etc. andupdate those models easily and quickly. Whatever the size of the model the program alwaysinforms the user of expected calculation times.

FORECASTS. Many data series vary over time in such a way as to make it difficult to determinethe underlying trend. AIDA pro-.ides two smoothing procedures to help identify that trend.namely: a moving average procedure and an exponential smoothing method. The user has fullcontrol over their critical parameters and a graphical display is produced to guide him in hisanalysis. Once a trend has been satisfactorily identified the program will fit a line to it andextrapolate the desired number of values into the future. Hard copies of the results may bereproduced using the plotterlprinter.

REPORT WRITER. This facility allows AIDA to present data in tabulated form. Prompted byquestions on the screen the user can make up a table from observations on various datasources with his own headings and footnotes, The user can control the width and size ofthe table and, when finished. transfer it to the printer. If required, the format of the tablemay be stored for future use.

SOME GENERAL POINTS ABOUT AIDA

THE SOFTWARE. AIDA is very user friendly and all interaction between the user and theprogram is in plain English. The program also includes a full data handling capacity (toallow data input, transformation and manipulation). The user can input; 5·day week obser·vations (with reference to an inbuilt calendar in AIDA), daily, weekly, quarterly and annualdata as part of the 'standard' AIDA program (other periodicities are available at specialrequest). There is also a 'missing' observations facility. Data transfer is possible from dist·to disc and thus there is unlimited data florage capacity. All AIDA programs are personalized with the purchaser's name and unique security password. AIDA is written in UCSDPASCAL

THE HARDWARE. AIDA needs an Apple II or ITT 2020 computer with 64K and two 5l"floppy disc drives. A visual display unit is also necessary. Optional: a colour monitor (toallow easy definition of three or more series graphed simultaneously), and a printer and/orplotter (to allow reproduction of screen text or graphics).

ED-SCI STATISTICS

A professional statistical calculation package f'or- the Apple II. Itincludes data entry and data file manipulation, statistical testing,usc of VisiCalc and Datadex Files, and file creation for Apple Plot.

STATISTICAL CALCULATIONS & TESTS

> Mean, Standard Deviation & Standard Error of the Mean> Coefficient of Variation> Frequency Distribution> Unpaired t-Test between 2 variables or between 1 and a constant> Paired t-Test> Chi-Square Analysis> Linear Regression with ANOVA and t-Tests of Significance> Correlation> One Way Analysis of Variance with the Newman-Keuls Test> Mann-Whitney U Test> Wilcoxon Paired-Sample Test

DATA ENTRY AND FILING

Data files are created by assigning variable names and defining thevariables as Alphanumeric or Numeric. Data values are entered foreach Case by Variable. There are full editing capabilities so variablenames and types can be changed at any time; data values· can be changedor deleted; and new variables and/or new cases can be added to an·existing data file. A pad of specially designed Data Entry Forms isincluded to assist the user with data entry.

The programs are self-explanatory and prompt the user with questionsat each step. The user orientation of the programs provides extensiveError-Trapping.

Missing data values are deleted either singly or in a p~ir-wise fashiondepending upon the specific statistical test or calculation.

The format of the statistics data files is described clearly in themanual so the uscr can write individualized programs that will storedata on the Data Disk to be read directly by the ED-SCI STATISTICS~rograms. Also. back-up copies of data disks can be made easily.

DATA FILE SIZE

There are three factors that go'vern the maximum size of a data file:(I) Number of Variables, (2) Number of Cases, and (3) Average lengthof the data values (in number of characters). An extensiv~ table isprovided in the instruction manual to assist the user in determiningthe optimum size of individual data files .. As an example, a data filewith 2 variables and an average data value length of 2 characters canhave 1,465 cas~s per variable for a total of 2,930 individual datapoints. A file with 5 variables and an average data value length of 4charilctcrs can have 500 cases per variable for tl total of 2,500individual data points. A file with 10 vDriables and average datuvalue length of 3 characters can have 300 c~ses per variable for atotal of 3,000 individual data values.

CREATE OR MERGE SUBF1LES

Subfiles can be created from master data files·in one of two ways:Subfiles can contain as many of the vart'ables from the master file asthe user wants and (1) all of the case values for those variables; or(2) only those cases that meet specific criteria set by the uscr.

EO-SCI STATISTICS has a Search and Select function where up to threedifferent criteria for inclusion into the subtile can be set (one foreach of three variables). Criteria include: <, =, >.'<>. >"". and <...Criteria can be set for both Alphanumeric and Numeric data. The usercan choose to include, for example. 6 of 10 variables in the subfileand set conditions for up to 3 of those variables. As an example. theconditions might be: Include only those cases where SEX = FEMALE andAGE> 20 and TEST SCORE >= 75. Only those cases that meet all threecriteria will be included in the new subfile.

Subfiles and master data files can also be merged. The Search andSelect feature and the ability to merge ftles provides the user withtremendous fle~ibility in manipulating data files. It is an excellentway to work with very large data files that can be broken down intosmaller units saving time and computer memory_

USE WITH APPLE PLOT

ED-SCI STATISTICS will create text files that can be read directly byApple Plot. This allows the user to display the data graphically.Apple Plot files can be created from individual variables or fr.om twovariables as X-V pairs. The linear Regression program will also createApple Plot files to plot a scattergram and the regression line.

USE WITH VISICALC ANO OATADEX

The 16 sector version of VisiCalc can create OIF files. A utilityprogram is included with EO-SCI STATISTICS that will convert theVisiCalc OIF file into an EO-SCI STATISTICS file. With this file,all statistical calculations a~d tests can be performed on theVisiCalc data. There is a similar utility program that will convertDATADEX files into ED-SCI STATISTICS files.

COMPUTER REQUIREMENTS

Microstat - 2.0 (New Rel. 3.0)

Features of Microstat Rel. 2.0 include: menudriven, the ability to declare each data file's numerical precision and drive location plus a Data Management Subsystem for file maintenance (edit, list, destroy, augment, sort, rank-order, move and merge) plustransformations (add, sUbtract, multiply, divide,reciprocal, log, natural log, and antilog, exponentiation and linear) that allow you to create new variables for existing variables.

Other features include: descriptive statistics (mean,sample standard deviation and variance, standarderror, minimum, maximum, sum, sum of squares, momentsabout the mean, skewness and kurtosis, and deviationsume of squares), Hypothesis tests (mean or proportion), Analysis of Variance (one-way, two-way and random blocks), Scatterplot (with overlapping pointsindicated), Correlation analysis, Simple, Multiple,and Stepwise Multiple Regression analysis (with support statistics), Time Series analysis, NonparametricTests, Crosstabls (including Chi-Square), Factorials,Permutations, Combinations, and Probability Distributions.

Mlcrostat Is not the nJn-of-the-mlll paCkage; the olgorlthms were selectedspecifically to reduce errors Introduced by the use of large numbers that arefrequently used In statistical calculatIons. To prove It. compare the sampleregression output In this flyer to the Infamous Longley data (Joumal of theAmerican Statistical Association, vol, 62. pp. 819-841) ond you will flnd thatMlcrostat outperforms some of the mainframe regression programs tested.SImilar techniques are used In other programs for maximum accuracy.

Each variable can have a maximum of 2,048 unique values.SpeedSTAT 2's data editor allows for easy insertion and deletion of variables and cases. A powerful set ofdata transform operations is built in.

SpeedSTAT provides a means of automatically accessing data from mostspreadsheet programs. Through use of the well-known DIF'· standard(Data Interchange Format), speedSTAT easily accepts data from manyother sources.

REGRESSIONS_dSTAT regression methods include:

• standard mUltiple linear regression• forward stepwise regression• forward selection regression• backward stepwise regression• backward elimination regression

For each data point, Regression will pro.vide the following information:

• predicted values of the dependentvariable

• residuals• standard error of the residual• standard errorof the prediction• leverage of the data point

~STAT will also compute the pre·dieted value for data points that are notIn the model. For each model, ANOVAtables are produced, which include:

• sum of squares tables with adjusted r'

."• coefficient of variation• root mean square

Parameters included are:

• estimate• degrees of freedom• t-value• Type Isum of squares• Type II sum of squares

Hardware RequirementsApple II, II Plus or lie with 48K and 2 disk drives

CORRELATIONThree types of correlation, and the cor·responding test values, are producedfor each variable:

• Spearman's Rho• Kendall's Tau C• Pearson Product-Moment Correlation

For each variable, speedSTAT 2 will alsoprovide simple descriptive statistics,Including:

COMMENTS: Based on Apple 11+ Users Manual Version 4.0.Not recommended for large surveys, more than 700 casesdue to loss of computational efficiency. File structure, observations in rows, variables in columns.Memory restriction on file size for 48K system isabout 1800 observations for 2 variables, less for alarger number of variables. Can split large filesflexibly, to handle a file of 500 observations and 10variables. File conversions for Mainframe, DIF, andVISlplot.

THE SfATlSTICIAN will compute the teststatistics for the following tests:single mean, single variance, differencein variances. Also one way and tWJ way1vlalysis of Variance can be performedand the associated ANOVA tables bepresented.

This component computes time seriesforecast using the follOWing models:moving averages, single exponentialsmoothirq, double exponential smoot.l"1irq,sinsusodial models, Holt's two parameterlinear exponential smoothirg, Winter'sexponential smoothing model, andadaptive filtering. Plots of forecastedversus observed data points can bedisplayed on the scre~n or plotted onthe printer. Also, a single series canbe plotted on the screen or printer.Mean Squared Error and Mean AbsoluteDeviation of the forecast are alsoprinted.

'!he followin; nonparametric tests can beperformed: Median test, Mann WhitneyTest, Kolmogorov-Smirnow, WilcoxonSigned Test, Kruskal-Wallis, Spearman'sRho, and the Runs Test.

The user can generate random variatesfrom the Uniform, Normal, Gamma,Exponential, SinomLd, Poisson, andGeometric random variables. This datais written to disk ~"J becomes part ofyour data base.

'n'1e user may generate some or all randomsamples of a given size from a data set.The program will calculate the mean,median, and variance of each sample andadd them to Y'Our data base. There is aspecial provision to provide histogramsof the mean and median values even ifthey are too nu:nerous to store on disk.

The package is available for the TRS-80 model I, II, and III and will soon beavailabe for the CFM operatirq sYstem.

MULTIPLEREGRESSIONANALYSIS

This component permits the user toestimate a linear model using one ofseveral estimation procedures includingstepwise, all SUbset, backwardelimination, ridge, and least squares.In addition to the estimates of thecoefficients, their t-values, andstandard errors, the User may display orprint the variance/covariance matrix,correlation matrix, ANOVA .table, Fstatistic, Durbin Watson statistic, andthe coefficient of detennination (R~2).

Moreover, the predicted values, observedvalues, and residuals can be plotted orlisted on the printer. In adnition thepredicted values can be saved to diskand be used in the estimation ofsimultaneous equations.

Technical Details

All data files used directly by DAISY (that is, used with theENTE, SAVE, EXAM, or OVER commands) have a name beginning withRDAISY.-. The commands are written so that this prefix need notbe entered.

The data files are stored as follows. First, the size of thetable is written, followed by the data, and finally the columnnames:

Element Contains======= ========

1 number of active rows2 number of active columns

3 value of row 1, column 14 value of row 1, column 2

0+2 value of row 1, column 0

0+3 value of row 2, column 1

c*r+2 value of row r, column c

c*r+3 name of column 1c*r+4 name of column 2

c*r+c+2 name of column c

If the application demands it, you can use non-DAISY files fromwithin DAISY by using your own extension routine.

ANOVA is actually four programs in one. Each program performs a specific taskmatched to the designed experiment under analysis. (I) A one-way ANOVA produces thetreatment sum of squre, mean square, and F ratio along with the error mean square.This algorithm accepts unequal numbers of replicates per treatment level and unlimitednumbers of treatment levels and replicates. (2) Two-way ANOVA performs an analysis ofeither fixed or random factors with equal numbers of replicates per cell. There is nopractical limit on the number of levels or replicates. Sums of squares and mean squaresare printed for both factors and the interaction as well as the error sum of squares andall F ratios. (3) The "N-Way" (for N up to 5 factors) will accept up to 4 levels per factoror any combination of levels not to exceed 1024 treatment combinations in 16K of core.Sums of squares and mean squares for all main effects and up to 3 factor interactions arecomputed. The appropriate (residual or pure error) mean square is used to compute the Fratios. (4) YATES analysis computes the mean square and half effect for two levelfractional experiments. All main effects and interactions are computed and printed out.In all programs except the YATES, the means for the main factors are printed.
